Today What is in tobacco that is addictive? Why is tobacco bad for you? What are the BAD parts in smoking? What does it feel like to be a smoker? What are the risks?
What Is Tobacco Addiction? When people are addicted, they have a compulsive need to seek out and use a substance, even when they understand the harm it can cause. Tobacco products—cigarettes, cigars or pipes, and smokeless tobacco—all can lead to addiction. Everyone knows that smoking is bad for you, and most people that do it want to quit. In fact, nearly 35 million people make a serious attempt to quit each year. Unfortunately, most who try to quit on their own relapse—often within a week.
Why is smoking addictive? Why do people struggle to quit? What’s in it that makes it so hard to stop?
NICOTINE … Addictive? YES! It is actually the nicotine in tobacco that is addictive. Each cigarette contains about 10 milligrams of nicotine. Seeing as the smoker inhales only some of the smoke from a cigarette, and not all of each puff is absorbed in the lungs, a smoker gets about 1 to 2 milligrams of the drug from each cigarette. Although that may not seem like much, it is enough to make someone addicted.
Is Nicotine the Only Harmful Part of Tobacco? NO! Nicotine is only one of more than 4,000 chemicals, many of which are poisonous, found in the smoke from tobacco products. Many of these other ingredients are things we would never consider putting in our bodies, like tar, carbon monoxide, acetaldehyde, and nitrosamines. Tar causes lung cancer, emphysema, and bronchial diseases. Carbon monoxide causes heart problems, which is one reason why smokers are at high risk for heart disease.

How Is Tobacco Used? Tobacco can be smoked in cigarettes, cigars, or pipes. It can be chewed or, if powdered, sniffed. “Bidis” are an alternative cigarette. They come originally from India and are hand-rolled. Some teens think that bidis are less harmful than regular cigarettes, but in fact they have more nicotine, which may make people smoke more, giving bidis the potential to be even more harmful than cigarettes.
What about Hookah? Hookah tobacco comes in many flavors, and the pipe is typically passed around in groups. Although many hookah smokers think it is less harmful than smoking cigarettes, water pipe smoking still delivers the addictive drug nicotine and is at least as toxic as cigarette smoking.
What Are Other Adverse Health Effects? Tobacco abuse harms every organ in the body. It has been conclusively linked to leukemia, cataracts, and pneumonia, and accounts for about one-third of all cancer deaths. The overall rates of death from cancer are twice as high among smokers as nonsmokers, with heavy smokers having rates that are four times greater than those of nonsmokers.
